NEW QUESTION # 146
You have achieved ROSC (Return of Spontaneous Circulation) in a 77-year-old female. She remains unresponsive and her vital signs are BP 94/58, P 82, and R 18. In what position should she be placed?
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
After ROSC in an unresponsive patient, the left lateral recumbent position (also called the recovery position) is preferred to:
* Maintain an open airway
* Prevent aspiration if vomiting occurs
* Promote drainage of secretions
Supine or Trendelenburg positions increase the risk of aspiration. Elevating the head to 45° may reduce intracranial pressure, but it's not standard post-ROSC care in an unresponsive patient unless airway protection is ensured.

NEW QUESTION # 147
What are the proper procedures for performing CPR on a 9-month-old patient? Select the three answer options that are correct.
Answer: A,D,F
Explanation:
The correct answers are A. Check the brachial artery for a pulse, C. Use a compression depth of at least two inches, and E. Use the two-thumb-encircling-hands technique for two rescuers.
1. Check the brachial artery (A):
For infants (less than 1 year old), the correct pulse check site is the brachial artery, not the carotid.
"For infants, assess the brachial pulse."
2. Compression depth (C):
Infant chest compressions should be about 1/3 the depth of the chest, which is approximately 1.5-2 inches.
"Compress the chest at least one-third its depth (about 1.5-2 inches in infants)."
3. Two-thumb-encircling-hands technique (E):
When two rescuers are present, this is the preferred method because it:
Produces better compressions
Improves perfusion
"Use the two-thumb encircling technique for two-rescuer infant CPR."
Why the other options are incorrect:
B). Compression rate is over 120/min # IncorrectCorrect rate is 100-120/min, not over 120 D). Compression area just above nipple line # IncorrectCorrect location is just below the nipple line on the sternum F). Ventilate one breath every 3 seconds # IncorrectWith advanced airway: 1 breath every 2-3 seconds (20-30
/min), not fixed at 3 seconds
Exact Extracts (NREMT/AHA-aligned references):
"Check the brachial pulse in infants."
"Compression depth should be at least one-third the chest diameter."
"Use the two-thumb encircling technique for two rescuers."
"Compression rate is 100-120 per minute."
Clinical Priority Summary:
Proper infant CPR includes brachial pulse assessment, correct compression depth, and appropriate technique, making A, C, and E correct.

NEW QUESTION # 148
A 38-year-old patient is dyspneic and has facial swelling after eating at a restaurant. What should the EMT do first?
Answer: A
Explanation:
The correct answer is C. Administer epinephrine.
This patient is presenting with classic signs of anaphylaxis, a life-threatening allergic reaction:
* Dyspnea (respiratory distress)
* Facial swelling (angioedema)
* Recent exposure to a likely allergen (food)
Why C is correct (Epinephrine):
Epinephrine is the first-line, life-saving treatment for anaphylaxis. It works by:
* Dilating bronchioles (improving breathing)
* Constricting blood vessels (improving blood pressure)
* Reducing airway swelling
NREMT-aligned guidelines state:
* "Administer epinephrine immediately in patients with signs of anaphylaxis."
* "Do not delay epinephrine administration in life-threatening allergic reactions." Why the other options are incorrect:
* A. Provide oxygen: Important, but not the priority over epinephrine in anaphylaxis.
* B. Initiate rapid transport: Necessary, but after immediate life-saving intervention.
* D. Obtain vital signs: Should not delay treatment in a critical patient.
Key Concept:
* In anaphylaxis, epinephrine is the first and most critical intervention.
* Delays in administration significantly increase mortality risk.
Exact Extracts:
* "Epinephrine is the drug of choice for anaphylaxis."
* "Immediate administration is critical in respiratory distress with allergic reactions."
* "Airway swelling and bronchoconstriction must be rapidly treated."

NEW QUESTION # 149
A 19-year-old patient has received multiple stab wounds. The patient is unresponsive. The vital signs are BP
82/60, P 116, R 28, and SpO2 86%. Which substance would the EMT expect to increase in the patient ' s body?
Answer: C
Explanation:
The patient is in hypoperfusion (shock) from blood loss. In shock states, tissues are deprived of oxygen, leading to anaerobic metabolism, which produces lactic acid as a byproduct. This causes metabolic acidosis, which is a critical sign of systemic oxygen debt.
Carbon dioxide rises with respiratory failure, but lactic acid is a more specific indicator of cellular hypoxia.

NEW QUESTION # 150
Which of the following assessment findings indicates respiratory failure?
Answer: B
Explanation:
NREMT distinguishes respiratory distress from respiratory failure. Respiratory distress includes compensatory signs such as tachypnea, accessory muscle use, and diaphoresis. Respiratory failure occurs when those compensatory mechanisms fail and the body can no longer maintain adequate oxygenation or ventilation.
Option D (Altered mental status) is the most reliable indicator of respiratory failure. According to NREMT, hypoxia and hypercapnia directly affect brain function, leading to confusion, agitation, lethargy, or unresponsiveness. This indicates that oxygen delivery to the brain is no longer adequate.
Option A is common in early respiratory distress.
Option B indicates increased work of breathing but not failure.
Option C reflects sympathetic activation, not failure.
NREMT teaches that mental status changes are late and ominous signs, requiring immediate airway and ventilatory support.
